Detailed Description
Referring to fig. 1 and fig. 2, fig. 1 is a schematic block diagram of a sniffing method in a high mobility backbone communication system proposed by the present invention, and fig. 2 is a user registration database and a registration database data record in the high mobility backbone communication system proposed by the present invention. The invention comprises the following steps:
the network management configuration creates a registry database, the data format and content of which are shown in fig. 2. And the network management issues the configured registration database to the high-mobility backbone network node equipment.
In the highly mobile backbone communication system, in order to adapt to the use requirement of the network, the node is mobile, the user moves, and the user identification adopts a plurality of addressing modes, including the forms of user names, telephone numbers and resource locators. And pre-distributing a network-wide unique identifier for the network-wide users through network management to form a registered data record comprising the network-wide users.
The user name form, which adopts text format to identify the user, such as: the lightning bolt is simple and easy to remember for a user, and when other users communicate with the user, the current position of the user can be inquired by simply inputting the name and searching a position server through a network access node. By adopting the method, the real identity of the user can be kept secret, for example, lightning is distributed to a specific user, the real identity of the user is hidden in the whole network, and even if the network is attacked, an adversary cannot easily guess the identity attribute of the user.
In order to continue the old usage habits and interworking with other networks, addressing of telephone numbers is also used. The number format can be unfixed in consideration of the combat requirements; this number must remain unique throughout the network, allowing for user mobility.
In the high mobility backbone network, a resource locator format user addressing mode can adopt a ' user name @ exchange node name and network number ' format, wherein the exchange node name represents a nickname configured for a certain exchange node by network management, for example, the network number ' skynet one ' represents 18 th army, the exchange node 3 in the 18 th army network is configured as a ' predator ', and then ' cheetah @ predator ' and skynet one ' represent a user cheetah registered on the 18 th army node 3. When session control is carried out, firstly, a switching node of a registration place is inquired; if the user moves to another node, the name remains the same and the user location is located by sniffing. Meanwhile, the method is easy to remember, and the real identity of the user is hidden outwards.
The implementation step (r) involves the network management configuration user registration data 1, the high mobility backbone network node device 9-1 and the high mobility backbone network node device 9-2 in fig. 1.
And step two, configuring a registration database. After receiving the configuration data issued by the network management, the node equipment records and forms a registration database including users with authority in the whole network.
In the high mobility backbone network, each switching node keeps a registration user record of the whole network, and the registration record is issued by network management to form a registration database. If the user records an address with a resource locator format in the registration database, the user is considered to be affiliated, for example, the attribution of 'predator' is 'cheetah @ predator, skynet number', namely the user belongs to the 18 th army node 3; if the user record does not contain the information, the user is considered to have no specific attribution, the registration of the user after random movement into any node is not influenced, and the position query of the user can be finished through mechanisms such as registration, address updating and the like.
The implementation step is completed by the configuration registration database 2 and the configuration registration database 10 in fig. 1, and the user name, the user number, the user resource locator, the gateway address and the user attribute are recorded in the databases.
And thirdly, the user registers after accessing the network and establishes a registration database.
According to the combat requirement, the switching node needs to be maneuvered and moved by the user. In the maneuvering and moving process, a user needs to register on the node equipment with successful access attachment. Each switching node in the high mobility backbone network stores the learned registered user information in the whole network to form a registration database. An example of the format and content of the registration database is shown in fig. 2.
And the implementation step is completed by a user registration database 3 formed by the user 4 and the user registration and a user registration database 11 formed by the user 8 and the user registration in the figure 1, and when the user accesses the node equipment, a registration message is sent to the node equipment. After receiving the registration information of the user, the node equipment inquires a registration database, and if the user record and the authentication pass, the node equipment records the user information in the registration database to form a registration data record. When the user moves, if there is a logout message, the user record is deleted in the registration database. If there is no logoff message, the record cannot be deleted. Thereafter, as the called party, the session answer message cannot be sent, and the calling party recognizes that the called party has moved.
When the calling user initiates a session, firstly inquiring a local registration database, and if a record exists, sending a session message to the recorded address; if no record or no session response message exists, the calling user searches a registration database, if no user record exists, the call fails, if the user record exists, the calling user can realize that the called user moves, and a sniffing message is sent to other nodes. The implementation step (4) is completed by the user 4, the registration database 5, the registration database 6, the sniffing message 7 and the high mobility backbone network node device 9-1 in fig. 1.
Receiving node device of sniffing message, inquiring user register database, if not checking user record, then not responding any message. If the user record is inquired, a session application message is sent to the address of the user, and if the session response message of the user does not exist, the user is indicated to be registered at the node before, but moves to other places without logout, and the user response message is not generated. If the user is still accessing this node, the user generates a session response message.
If the session response message of the called user is not received, the fact that the user is not at the node is indicated, and the node cannot send a response message of successful sniffing back to the calling node device. And if the session response message of the user is received, sending a response message of successful sniffing back to the calling node equipment and simultaneously carrying out the session establishment process.
The implementation step is completed by the high mobility backbone network node device 9-2 in fig. 1, the sniffing message 14, the query registration database 13 and the user 8.
Sixthly, the calling node equipment receives the response message of successful sniffing, records the address of the called user in the registration database and continues the rest conversation process at the same time.
The calling node device that receives the response has added this record in its own registration database, and then does not need to start the sniffing method again when the communication session is carried out again later.
The implementation step is realized by forming a registration database 3 by the high maneuvering node equipment 9-1, the sniffing message 7 and the user registration. Therefore, the sniffing method of the high mobility backbone network user is completed, the position of the called user is found, and the communication session service is carried out at the same time.
And completing the communication session service of the high mobility backbone network.
